  • Alert level at Clevelandraised as a new lava dome becomes evident
  • A significant increase in seismicity at Nevado del Ruiz brings a rise in the alert level
  • High levels of sulphur dioxide emissions at Soufrière Hills
  • Another paroxysmal eruptive episode at Etna with lava fountaining and ashfall

The latest Smithsonian Institution and United States Geological Survey Weekly Volcanic Activity Report has been published by the Global Volcanism Program, covering the week 14-20 March 2012. The report is compiled by Sally Kuhn Sennert. Among the highlights of this week:

  • A plume, probably water vapour, seen from Iliamna, where seismicity remained elevated
  • Seismicity decreased at Nevado del Ruiz but significant gas emissions continued
  • Etna continued lively with lava flows and fountaining, and strong ash emission
  • Daily explosions at Shiveluch produced plumes which reached 3-5 km altitude

The latest Smithsonian Institution and United States Geological Survey Weekly Volcanic Activity Report has been published by the Global Volcanism Program, covering the week 29 February to 6 March 2012. The report is compiled by Sally Kuhn Sennert. Some of the highlights of the volcanic week:

  • Continuing activity at Etna including strombolian eruptions, lava fountaining and lava flows
  • Explosions at Fuego produced plumes that reached 0.6 km above the crater
  • Plumes rose to 1 km above Puyehue-Cordón Caulle as low-level eruptive activity continues

Time speeds up in Sicily: an Etna enigma? 11 July 2011

Posted by admin in Etna, Italy.

Sicily’s Mount Etna has been having a lively time of it over the past few days: there will be a more detailed report here soon. For the moment, here’s a bizarre thing. Did the most recent eruption on 9 July affect electronic clocks across Sicily, setting them fifteen minutes fast? The UK’s Daily Mail ‘newspaper’ seems to think so. However, the Italian press was reporting on this strange Sicilian phenomenon more than a month ago (as the Mail‘s reporter would have found out, had they bothered to check). Here’s an Italian television news report from 9 June 2011, for example. The Corriere della Sera pointed out on 11 June that the alleged misbehaving clocks have been reported across the island, not just around Etna, suggesting that the volcano’s electromagnetic woo waves, or whatever, are not to blame.

UPDATE. Dr Boris Behncke of the INGV e-mails to say: ‘As for the clocks, none of the clocks that we have at home – 15 km from Etna’s summit – have shown any anomalous behavior’. Boris goes on to suggest that ‘this is one of those bulls**t things put into circulation on the internet’ to keep things ‘a bit metaphysical’.

Etna is stirring and might be ready to put on a show … time to watch the webcams, perhaps. Thanks to the Sage of Etna Boris Behncke and to Erik Klemetti for keeping us informed about the changing moods of the giant of Sicily.

The Smithsonian Institution and United States Geological Survey Weekly Volcanic Activity Reports enter their second decade of chronicling what the world’s volcanoes are up to with this week’s report, which covers 29 December 2010 to 4 January 2011 and is compiled by Sally Kuhn Sennert. Some selected highlights:

  • Etna: light ashfall, incandescence, vigorous strombolian activity
  • Manam: new eruptive episode – ash plumes, some dense; incandescence; pyroclastic flows
  • Stromboli: increase in the frequency and intensity of explosions from the S1 vent
  • Machín: increase in low-magnitude volcanic-tectonic seismicity recorded

The Daily Volcano Quote: Vesuvius insufficiently sublime 23 September 2010

Posted by admin in daily volcano quote, Italy, Vesuvius.
comments closed

One who had never seen a volcano, might conceive of its fires bursting up from their fountains, amidst ponderous rocks and boundless chasms, lurid in the hues of Phlegethon: and the sublime might there rejoice in the semblance of hell and chaos. But Vesuvius has little of this. A dull monotonous mantle covers all, as the waters of the ocean fill its bed: a colourless pall of ashes, or ashy lava, chokes the whole mountain from topmost ridge almost to its utmost base, where Spartacus and his gladiators entrenched in caverns once held their foes at bay, so that on a near approach the sublimity of the volcano, when it is not in conflagaration, vanishes. Yet Nature at her work for man as in the earth’s infancy she wrought ere man was, or human eye could witness her genial labors – this constrains our thoughts to primordial themes, and they may be sublime though the mountain be not.

An anonymous author tries not to be disappointed by Vesuvius in ‘Leaves from the journal of a traveller’, The Metropolitan Magazine, October 1837, p. 226.

INGV head ponders keeping seismic data secret 15 September 2010

Posted by admin in Italy, natural hazards.
comments closed

Dr Enzo Boschi, director of the Italian Istituto Nazionale di Geofisica e Vulcanologia, when not thinking aloud about Marsili seamount erupting and unleashing a tsunami on Southern Italy (‘it could happen tomorrow’), is concerned that the easy availability of scientific data in the non-specialist public arena is causing unnecessary fear and alarm. Perhaps, for example, the seismic data collected by the INGV should not be published? The media, says Boschi, distort the data and act as scaremongers, spreading panic and feeding the ‘prophets of doom’.

Apparently Boschi may just have been joking about halting the publication of data. But he will certainly have had his reasons for floating the idea.

IMPORTANT NOTE: please take the time to read an invaluable comment on this issue (also cross-posted to this thread at Eruptions) from Boris Behncke of the INGV.

UPDATE. Interesting sidelights on the Chinese approach to earthquake science in this article in New Humanist magazine: ‘An official from China’s national earthquake administration spoke positively on the programme about parrots that can predict tremblors and the paranormal abilities of a man who claimed he heard ringing in his ears before the April earthquake in Yushu, northwest China’. Following the Tangshan earthquake of 1976, which killed around 240,000 people, ‘Officials were singled out for having ignored purported natural indicators of disaster: these apparently included the migration of yellow weasels and unusually large catches of fish’. Italian seismologists have their problems, but things could be worse.
